High-energy x-ray photoelectron spectroscopy Cr <i>Kα</i> measurement of bulk dysprosium

High-resolution soft X-ray photoelectron spectroscopy of liquid water.

High-resolution soft X-ray photoelectron spectra of liquid water (H(2)O and D(2)O) were measured using a liquid beam photoelectron spectrometer. The 1a(1) (O1s) band and the lowest valence 1b(1) band had single peaks, which is not consistent with the split 1b(1)→ 1a(1) of the X-ray emission band of liquid water if the splitting is assumed to originate from level shifts in two different hydrogen...

X - Ray Photoelectron Spectroscopy of Silicate Glasses

X-ray photoelectron spectroscopy (XPS) is a powerful technique capable of providing unique information about the structural chemistry of glasses. However, inappropriate procedures for the preparation of sample surfaces or the lack of reliable methods to overcome electrostatic charging effects during analysis of dielectric materials can cause spurious features to be introduced or intrinsic featu...

Chemical order in GexAsySe1-x-y glasses probed by high resolution X-ray photoelectron spectroscopy

Quantitative characterization of DNA films by X-ray photoelectron spectroscopy.

We describe the use of self-assembled films of thiolated (dT)25 single-stranded DNA (ssDNA) on gold as a model system for quantitative characterization of DNA films by X-ray photoelectron spectroscopy (XPS). We evaluate the applicability of a uniform and homogeneous overlayer-substrate model for data analysis, examine model parameters used to describe DNA films (e.g., density and electron atten...

Surface Characterization of Titanium Powders with X-ray Photoelectron Spectroscopy

Electron Beam Melting (EBM R ©) is a near-net-shape additive manufacturing technology developed by Arcam AB, where Ti-6Al-4V alloy powder is commonly used to manufacture medical implants and components for the aerospace industry. Although Arcam has developed special specifications of some parameters for the powders, the powders from different manufacturers do not behave in the same way in the E...
